I'm confused about this: "Confidentiality has been a key strategy for Microsoft" From an article about Microsoft patents and Android. Link: http://arstechnica.com/gadgets/2015/02/microsoft-and-samsung-settle-android-patent-royalties-dispute/
The part that I'm confused about is that it sounds like Microsoft isn't releasing the information about the patents that Samsung. Even if the confidentiality is between Microsoft and Samsung, it's still confusing to me. The reason it's confusing is how would a person (or business) know if they are developing something that's in violation of Microsoft's patent?
I understand (could be wrong) that during the approval process the patent information can be private, but after a patent is approved, wouldn't Microsoft be forced to say exactly what patents are at issue?
Second part: Can a person claim a patent on a product without saying what the patent covers? In other words, file a patent, build the product, identify that the product is patent pending and not have any obligation to say what is covered by the patent.
If not, what exactly is confidential about what Microsoft is doing?
